The MRRC will continue to support a secure data environment at the Institute for Social Research, (the Data Enclave), where researchers can analyze Social Security administrative files without risking a breach of confidentiality. While this is an important resource, travel to the site remains a significant obstacle for many potential users, since users must be physically present to use the enclave facilities. To deal with this problem, we have developed an alternative method for access to the enclave: a remote workstation connected to an enclave server via a virtual private network (VPN) connection that emulates (in hardware and software) a dedicated data communications line. Further enhancements will be made to the VPN during the coming year
